In ecosystems, plants transform light energy from the Sun into chemical energy when they make sugar. This sugar can then be consumed by other organisms to be used as building blocks for other molecules, such as proteins and fats, or it can be transformed into other forms of energy, such as kinetic energy, when the organism moves. Which of the following statements is supported by the above information? A. Matter can change forms, but only one kind of energy exists. B. Energy can change forms, but only one kind of matter exists. C. Matter and energy can change forms and locations in ecosystems. D. Matter and energy must always remain in the same form and location.

am i too late?

explanation:

the increase of protons   hope this

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
